8 Claims. (Cl. 221-148) This invention relates 'to bottle closures foropening 6 and outof the closure member. For sealing the bottle as wellas regulating 'the'flow of this purpose acap I is threaded into theupper liquid from the bottle and the invention has for portion of theclosure member so that the botits principal object to provide a bottleclosure of tom of the cap may be seated and un's'eated on simple andinexpensive construction with which the gasket 8 which surrounds theopening 6, and 5 a bottle may be quickly and easily sealed or the thusprovides a seal over' the opening when the flow of liquid from thebottle accurately regulated cap is threaded thereagainst. in dispensingthe contents thereof. The. cap I is'provided with an overhanging Thisand other objects and attendant advanflange 9 andthis flange is extendedfrom the 10 tages of the invention will become more readily periphery bya short lug Ill. The underside 01 10 apparent from the detaileddescription thereof this lug is grooved and its groove l2 extendsinwhich follows, reference being had to the accomwardly of the cap toform the continuation of a panying drawing in which: v 7 vertical grooveor duct l3 provided in the pe-v Figure 1. is an enlarged top plan viewoi the ripheryof the threaded portion of .the cap. combined bottleclosure and liquid dispenser.

A gasket 19 with a central opening 20 is placed againstthe shoulder to have the neck 2| of a bottle threaded thereagainst tohold the gasket in place and have its central portion overhang theopening in the neck so as to provide a seat around the hole in thegasket.

A bottle cap 22 is threaded into the top of the body member so as toopen or close the opening 20 in the gasket and control the flow of theliquid from the bottle to the outlet duct 23 and open the vent thru theduct 24. overhangs the top of the cap, is provided on its under sidewith an annular groove 25 so as to have the top of the body memberengage thereinto and provide an additional seal at the top of the bodymember when the cap is screwed thereinto.- When the cap is unscrewed andthe bottle tilted to dispense some of its liquid the groove 25 keeps anyliquid which collects therein from flowing off the overhanging flangeexcept at the outlet groove 28 which is located under the tip 21 of thecap and is in line with the outlet duct for the purpose of directing theliquid as it leaves the bottle.

I claim:

1. In a combined bottle closure and dispenser the combination of anattachable closure member adapted to be fastened to the neck of a bottleor other container and having a restricting discharge opening therein, acap member movable in the top of said closure member so as to openandclose the restricted discharge opening within the closure member, anoverhanging projection at the top of said cap member, an air vent and aliquid outlet duct partiallyextending thru said cap member offset fromsaid discharge opening and a substantially horizontal extension at theend of said outlet duct leading to the edge of the projection at the topof said cap member.
